In what order do players choose battlefields and determine turn order across games in a best of 3 match?

Ruling: For all games in a match (games 1, 2, and 3), battlefields are revealed simultaneously by both players before turn order is determined. After battlefields are chosen, players then decide who goes first/second, followed by draw/mulligan.

Sequence:

• Both players select and reveal their battlefields simultaneously
• Determine turn order (first/second)
• Draw and mulligan
